To determine clinical outcomes for male and female patients aged ¡Ý40 years undergoing OCA compared with a group of patients aged <40 years. Cohort study; Level of evidence, 3. A review of prospectively collected data of consecutive patients who underwent OCA by a single surgeon with a minimum follow-up of 2 years was conducted. The reoperation rate, failure rate, and patient-reported outcome scores were reviewed. All outcomes were compared between patients aged <40 or ¡Ý40 years, with subgroup analyses conducted based on patient sex. Failure was defined as revision OCA, conversion to knee arthroplasty, or gross appearance of graft failure at second-look arthroscopic surgery. Descriptive statistics, Fisher exact or chi-square testing, and Mann-Whitney U testing were performed, with P < .05 set as significant. A total of 170 patients (of 212 eligible patients; 80.2% follow-up) who underwent OCA with a mean follow-up of 5.0 ¡À 2.7 years (range, 2.0-15.1 years) were included, with 115 patients aged <40 years (mean age, 27.6 ¡À 7.3 years; 58 male, 57 female) and 55 patients aged ¡Ý40 years (mean age, 44.9 ¡À 4.0 years; 33 male, 22 female). There were no differences in the number of pre-OCA procedures between the groups (P = .085). There were no differences in the reoperation rate (<40 years: 38%; ¡Ý40 years: 36%; P = .867), time to reoperation (<40 years: 2.12 ¡À 1.90 years; ¡Ý40 years: 3.43 ¡À 3.43 years; P = .126), or failure rate (<40 years: 13%; ¡Ý40 years: 16%; P = .639) between the older and younger groups. Patients in both groups demonstrated significant improvement in Lysholm (both: P < .001), International Knee Documentation Committee (IKDC) (both: P < .001), Knee Injury and Osteoarthritis Outcome Score (KOOS) (both: P < .001), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (both: P < .001), and Short Form¨C12 (SF-12) physical (both: P < .001) scores compared with preoperative values. Patients aged ¡Ý40 years demonstrated significantly higher KOOS symptom (P = .015) subscores compared with patients aged <40 years. There were no significant differences in the number of complications, outcome scores, or time to failure between the sexes. In patients aged <40 years, female patients experienced failure significantly more quickly than male patients (P = .039). In contrast, in patients aged ¡Ý40 years, male patients experienced failure significantly more quickly than female patients (P = .046).
